This is a quick guide to show you how you can upgrade your firmware on your MediaTek GPS module. The upgrade procedure is relatively easy as you only need to connect the module with your computer and then use a PC utility to upgrade the firmware.

What you need to upgrade/unbrick your MediaTek module

Step 1: Connecting Everything together

It is very easy to connect everything together with the adaptor. SImply press the male headers into your FTDI cable as shown in the image on the right, make sure it is connected the right way around.. Then simply lug the EM406 connector into the GPS module (it can only go in one way)

Downloading FTDI DriversIf you are using windows 7 the drivers for the FTDI cable should be installed automatically, however if not they can be downloaded here. The easiet option is to download the setup executable, and just follow the instructions to install the drivers.

Optional: Using FTDI cable with jumper wires.

If you are not using the FTDI-GPS adaptor you will need some male headers and 4x jumper wires as shown below.Put some male headers into the FTDI connector, and solder the headers onto the bottom of the MediaTek GPS module as shown below.
